Local highways provide a critical transportation link between the places we live, work, and play and also provide connections to state highways. Cities, counties and highway districts provide the necessary structure to enable the appropriate measures to keep this critical link functioning efficiently and effectively.

Local highway systems have 19,269 centerline miles of paved roads and 14,065 gravel and dirt roads, for a total of 33,334 miles of improved highways. Fifty-five percent of all commercial goods movements occur on local highways in Idaho, and 93 percent of local highway commercial traffic is concentrated on arterial and collector roads.

Idaho’s local highways have the highest collision rates as well as the highest number of injuries as compared to state highways.
